The second step is to calculateu=UΣ-1, consider theΣis diagonal matrix, thus the process can be implemented by a loop of calling BLAS ?scal function for computing product of a vector by a scalar. And the scalar for each column ofuwould be inverse of each non-zero element ofs...

In this paper, a family of simple formulas for the calculation of the pseudo inverse of a rectangular matrix of less than maximum rank is derived using linear vector space methods. The principal result is that the pseudo inverse of a matrix can be calculated as = , where and are ...

A complex vector space is said to be a Hilbert space if it has a scalar product and if it is complete, i.e., if all Cauchy sequences in converge to an element of . 1.2 The Best Approximant Theorem A subset A of a Hilbert space is said to be convex if for all u, v ∈ ...

P Soto-Quiros,A Torokhti 摘要: We propose two techniques for the fast numerical implementation of a random vector transform within Wiener filtering paradigm. In signal processing terminology, the transform is interpreted as an optimal filter. The proposed transform aims to minimize the sum of ...
